Replacement coils for use with the Bottom Coil Tank (BCT), which are now available for both the Inferno and Lavatube. Each pack contains 3 replacement single coils, with silica-wick wrap, available in choice of resistance: 2.5, 3.0 and 3.5 ohms for the Lavatube, 1.8 ohms for the Inferno.
The 2.5 ohm resistance is standard for the Lavatube and the recommended level, but you might like to try the 3.5 and 3 ohm ones when you have got the hang of it. However in the Inferno we suggest that you only use the 1.8 ohm, and possibly the 2.5 ohm, but not higher.
The life of a heating coil varies according to usage, but you'll know when it's time as the vaping experience will begin to degrade. Easily replaced, you simply remove the base, unscrew the central coil and carefully screw in the new one.
